Original application filed April 10, 1915, Serial No. 20,423. Dividedand this application filed February 17,1917. Serial No. 149,158. I I

To all whom it may concern:

Be it known that I, HARRY W. JoNns, a citizen of the United States,residing in San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Improvement in Paper Boxes,of which the following is a specification.

My invention relatesin general to paper boxes and has more particularreference to boxes of this character made of corrugated boardor otherstiff material and intended for use as containers for shipping matterby, parcel. post. It will, however, be manifest, as the invention isbetter understood, that it has a broader and more general application,being capable of efiicient use in. numerous other connections.

A principal object of the present invention is the provision of a strongand durable box of the general character described, which may beconstructed from blanks cut from a sheet of material without any-wasteof said sheet in the cutting of successive blanks.

A further object of the invention is the provision of a box of thischaracter which will have strong overlapping flaps at its open side orsides, said flaps being particularly formed to resist the rough handlingof the mails.

Other objects and advantages of the invention will be apparent as it isbetter understood from the following description when considered inconnection with the accompanying drawing illustrating a preferredembodiment thereof.

On the drawing,

Figure 1 is a plan elevation of a strip from which blanks may be out toform a box embodying my invention and showing a blank as cut therefrom;I

Fig. 2 is a view of a blank scored, cut and ready for folding;

Fig. 3 shows the blank folded and with the edges scored ready to beopened to form a finished box;

Fig. 4 is a view of the box having the securing edge strip removed toshow the relative relation of the top and bottom flaps; and

Fig. 5 shows the completed box.

The box embodying my invention and shown on the drawing is ofrectangular form, being slightly longer than it is wide. In the presentinstance, this box consists of two end walls 6, two side walls 7 andtops and bottoms formed of flaps 8 on the edges of the side walls andflaps 9 on the edges of the end walls. These flaps arearranged in thefinished box with abutting edges so that two thicknesses of corrugatedboard of which this'box is formed are provided at the top and bottom.The edges of the side flaps 8 abut as do also the edges of the end flaps9 and they meet in inclined lines as in- 1 tance between its parallelsides is equal to the sum of the horizontal dimensions ofa s1de and anend. In planning a blank there fore, an end and sidev are first laid outasindicated at a and b in Fig. 2, a equaling in superficial area anddimensions an end 6 and biequaling in superficial area and dimensions aside 7. The inclined lines fornp ing the sides of each trapezoidal partare each determined by locating a point 0 outwardly of the center of alateral side of b a distance equal to one-half the length of the lateralside of a, and a second point (Z located outwardly of the center of alateral side of a, a distance equal one-half the length of a lateralside of I) and drawing a line through these two points intersecting theparallel sides of the trapezoidal part. The trapezoidal part isduplicated with the center of a short parallel side of the. one partcoinciding with the center of the longer parallel side of the otherpart. This blank is scored centrally throughout its length along lines 6defining the lateral edges of the box and along the lines 7 atrightangles thereto which, in the finished structure, define the end edges orrather the vertical edges of the box. The portionswithout the lines 6form the flaps, and these portions are cut inwardly to the lines f fromeach side as in-- dicated at g to separate the flaps from each other.When a blank-has been constructed in accordance with Fig. 2 and theforegoing description, one trapezoidal part may be lald back over uponthe other as indicated in Fig. 3 and the binding strip 11 of lengthequal to the height of the box pasted over the edges thus adjoining.Thereafter the completed box need only be opened up, bringing a rightangle at each line 7 and the flaps folded down into position.

The blank thus described may be cut without waste from a continuousstrip of material of Width equal to the combined altitudes of the twotrapezoidal portions. This is done by alternately reversed cuts asindicated in Fig. 1, the tapering of the trapezoidal parts of one blankextending toward one side oi the strip or sheet from which the blanksare being cut and the tapering of the parts of the next toward theopposite side. This effects not only a substantial saving of thematerial but also a substantial saving in the cutting operation, as eachsuccessive out along the broken. line formed by the side of the blankproduces a completed blank, it only being necessary in the strip to cutcom pletely across it to produce each blank.

It is thought that the invention and many of itsattendant advantageswill be understood froin the foregoing description, and it Will beapparent that various changes may be made in the form, construction andarrangement of the parts Without departing frointhe spirit and scope ofthe invention or sacrificing any of its material advantages, the formhereinbeiore described being merely a preferred embodiment thereof.

This application is an officially required division of my applicationfiled April 10, .1915, Serial No. 20,423, granted as Patent 1917, forart of of said flaps being disposed obliquely with respect to the sidesand ends of the box.

2. box comprising a body provided With abuttin side flaps at its top andbottom and abutting end flaps at its top and bottom,

each of said flaps being of trapezoidal form and the abutting edges ofsaid flaps being disposed obliquely with respect to the sides and endsor the box.

8. A box having abutting side flanges and abutting end flanges andformed of a double trapezoidal blank.

' 4. A box formed of a blank, each blank being composed of twotrapezoidal parts, and each tra oezoidal part being subdivided on linestransverse to the converging sides to form separate flaps. y

A blank for a paper box composed of trapezoidal sections joinedcontiguously, the shorter parallel side oi one section directly to thelonger parallel side of the other section, each section being subdividedto form separate flaps.

6. A blank for use in forming a paper box comprising a plurality ofjoined trapezoidal sections, the said sections being directly joined oneto another at their parallel sides, the short side of one section to thelong side of the other section.
